Closure type slope green plant irrigation and water distribution method

Abstract

The invention discloses a closure type slope green plant irrigation and water distribution method. Irrigation water is controlled to enter an irrigation pipe network from the upper end of a main channel water pipe vertically arranged on a slope, enters multiple horizontal water supply pipelines communicating with the main channel water pipe, and then permeates into slope planting materials; and the method is characterized in that the ends, connected to a main channel, of the horizontal water supply pipelines adopt a closure method during water supply, so that the irrigation water that is regularly and quantitatively supplied can be intercepted to enter the horizontal water supply pipelines, and then water permeation and distribution on the slope can be performed, and therefore, the irrigation on the green plants on the slope can be realized. The method can better guarantee that each horizontal water supply pipeline can intercept and be distributed with enough irrigation water, so thatthe average distribution of water resources can be better guaranteed, and irrigation uniformity can be enhanced.

Description

technical field [0001] The invention relates to the technical field of ecological restoration and greening, in particular to a water-closing method for watering and distributing green plants on slopes. Background technique [0002] Due to the mining of mineral resources and road construction in arid and semi-arid areas, the topography and ecological environment of a large number of closed mines and roads have been severely damaged, and many rocky slopes with large and high slopes have appeared. Usually, these high and steep rocky slopes are not covered by vegetation, have small rainfall area, and poor water holding capacity. In addition, there is little rainfall in arid areas and unstable rock masses exist on the slopes, making it extremely difficult to restore vegetation on the slopes. And it is easy to cause geological disasters such as landslides and rockfalls because the ecology cannot be restored, seriously affecting the ecological environment. Therefore, it is urgent ...

AI Technical Summary

Problems solved by technology

However, the vegetation restoration technology for high and steep rocky slopes in arid areas is still immature. Two conventional restoration technologies are used to restore vegetation on high and steep rocky slopes in arid areas, and there will be the following problems: (1) Difficult construction and high cost

Three-dimensional net spraying technology, the workload of bolting on high and steep rock slopes is heavy and dangerous, and the construction cost is high; stacking vegetation bags is dangerous when stacking vegetation bags on high, steep and unstable rock slopes High performance, heavy workload, thick planting bag, high cost

(2) Applicability is limited by the complex terrain environment

(3) There is no support for rock blocks on high and steep rock slopes

(4) It is impossible to collect and store rainwater and automatically adjust the amount of irrigation water. The single vegetation soil layer has poor water retention, so it cannot provide long-term sufficient water for vegetation on high and steep rocky slopes in arid areas. Vegetation restoration takes a long time and the effect is poor. The cost of cultivation is high

However, the following defects still exist: 1. simple anchoring cannot provide sufficient strength support effect, and deeper anchoring has defects such as difficult operation, high anchoring risk, and reduced slope stability.

2. At the same time, rainwater is directly collected for spray irrigation. The rainwater is also easy to contain dirt and cause pipe blockage. The electric control equipment for sprinkler irrigation in the field environment is restricted by power supply conditions and is prone to failure; High, and not conducive to long-term maintenance
